Description

Technical Field

[0001] The present invention relates to the technical field of knitting machines, and in particular to a knitting machine capable of reducing noise. Background Art

[0002] Circular looms are used to weave tubular fabric. The loom's warp frame features numerous spindles, and a specific number of warp yarns are used, depending on the width of the fabric and the tape. Before entering the loom, the warp yarns are spun by a warp frame. The weft shuttle then weaves the weft yarns in a circular motion through the spun yarns, forming the tubular fabric.

[0003] Among the circular knitting machines currently on the market, those with 16-1000 spindles all operate on a gear combination in a circle. A pull-up disc rotor is provided at the corresponding position of the gear. There are four notches on the surface of the pull-up disc rotor, and a spindle seat corresponding to the left and right runways of the panel is installed on the notch. The raw yarn spindles for braiding ropes are installed on the spindle seats. After the equipment is started, the gear transmission drives the spindle seats on the pull-up disc to cross the left and right runways in a circular row to obtain a cross-woven fabric. When the equipment is cross-woven, the spindle seats are all in the same position. The simultaneous collision during use makes the equipment noisy and unstable.

[0004] Therefore, we propose a knitting machine with reduced noise to solve the above problems. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a knitting machine with reduced noise to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A noise-reducing braiding machine comprises a plurality of rotors, wherein the rotors are divided into a plurality of groups, each group of rotors is distributed on a circumference, an annular array of slots is arranged on the rotors, and spindle seats are arranged in the slots.

[0008] Preferably, the rotor is plugged into the fixed shaft, and the fixed shaft is meshed with the rotor gear.

[0009] Preferably, the rotor gear is meshed with a driving gear that is coaxially fixedly connected to the output shaft of the motor through a bridge gear.

[0010] Preferably, the fixed shaft is rotatably inserted into the connecting seat, and the connecting seat is arranged on the braiding machine body.

[0011] Preferably, a through hole is provided at the bottom of the spindle seat, a guide block is inserted into the through hole, and the guide block slides in a track on the edge of the rotating seat.

[0012] Preferably, the track is an annular guide rail arranged around the edge of the rotating seat, the guide rails around adjacent rotating seats are connected, the guide rails include a first guide rail and a second guide rail, and the connection between the annular guide rails around two adjacent rotating seats forms an X-shaped intersection.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. During the design process, different inner angles are designed to create a non-circular panel. The spindle seats on the panel can be separated and crossed in sequence at different angles. Compared with the existing technology, when several spindle seats are cross-switched on the track, only two spindle seats are switched at the same time under any circumstances. This makes the equipment run smoothly, the noise is greatly reduced, and the service life of the equipment is extended.

[0015] 2. When several spindle seats switch tracks above the panel, at most only two spindle seats will switch at the same time at any time. Compared with the existing circular knitting machines with different spindle numbers, no matter the number of spindles is fixed-axis hole spindles, spindles, spindles or even more spindles, only two spindle seats will switch tracks at the same time. Therefore, for circular knitting machines with more spindles, the width of the inner angle design will be larger, and the noise reduction effect will be more obvious.

DETAILED DESCRIPTION

[0037] like Figure 1-13As shown, a noise-reducing knitting machine includes a panel 4, a rotating seat 8 is provided on the panel 4, a fixed shaft 17 is rotatably connected in the rotating seat 8, the bottom end of the fixed shaft 17 is fixedly connected to the rotor gear 10, the fixed shaft 17 is inserted into the connecting seat 14 and rotates with the connecting seat 14, the top end of the fixed shaft 17 is inserted into the fixed shaft hole 16 on the rotor 13, four card slots 15 in a circular array are provided on the side of the rotor 13, the card slots 15 are engaged with the spindle seat 19, and the spindle seat 19 is provided with a through hole 21 for inserting a guide block 22, and the guide block 22 is on the first track 6, The first and second tracks 6 and 7 are arranged on the outside of the rotating base 8, and the first and second tracks 6 and 7 intersect at the close position of two adjacent rotating bases 8 to form an X-shaped intersection 9. The rotor gear 10 is on the knitting machine body 1 below the panel 4, and the knitting machine body 1 is fixed on the frame 2. The rotor gear 10 is engaged with the driving gear 12 rotatably connected to the knitting machine body 1 through the bridge gear 11. The driving gear 12 is coaxially and fixedly connected to the output shaft of the motor 5. The motor 5 is electrically connected to the control box 3 fixed on the knitting machine body 1.

[0038] The servo motor 5 is started through the control box 3. The output end of the servo motor 5 drives the driving gear 12 to rotate. The rotating driving gear 12 drives the bridge gear 11 to rotate. The bridge gear 11 drives the rotor 13 gear to rotate. Since the rotor gears 10 are engaged with each other, the rotation directions of the two adjacent gears in the rotor gear 10 are opposite. The rotor gear 10 drives the rotor 13 above the panel 4 to rotate through the threaded column 18. When the rotor 13 is aligned with the slot 15 of the adjacent rotor 13, the position of the spindle seat 19 is adjusted.

[0039] The two guide blocks 22 below the spindle seat 19 are inserted into the first track 6 or the second track 7. When the spindle seat 19 moves to the X-shaped intersection 9, the slot 15 clamps the cylindrical structure left after the groove 20 is opened in the spindle seat 19, so that part of the spindle seat 19 moves from the first track 6 along the X-shaped intersection 9 to the second track 7. At this time, the guide block 22 continues to slide in the second track 7, but moves from the first track 6 to the second track 7. At the same time, part of the spindle seat 19 moves from the second track 7 along the X-shaped intersection 9 to the first track 6. At this time, the guide block 22 continues to slide in the first track 6, but moves from the second track 7 to the first track 6.

[0040] In the following embodiments, the angle between the line connecting two centrosymmetrical slots 15 on the rotor 13 and the line connecting the centers of two adjacent rotors 13 is the entry angle, and the angle formed by the lines connecting the centers of three consecutive rotors 13 is the interior angle. The diameter unit is mm.

[0041] Example 1

[0042] like Figure 14-15As shown, taking 24 spindle seats 19 as an example, 12 rotating seats 8 are set on the panel 4. Each rotating seat 8 is rotatably connected to a fixed shaft 17, and the fixed shaft 17 is connected to the rotor 13. The 12 rotors 13 are divided into two groups and distributed on two circles with diameters of 332.6 and 356.92 respectively. There are 6 with an internal angle of 135° and 6 with an internal angle of 165°. Four annular array slots 15 are set on the edge of each rotor 13, with 6 cutting angles. Figure 15 It is a schematic diagram after the rotor 13 rotates 90 degrees.

[0043] In the above scheme, when the rotor 13 rotates, the spindle seats 19 are switched separately, that is, only a single spindle seat 19 is switched on one side, and at most only two spindle seats 19 are cross-switched on the left and right tracks in both directions. Compared with the existing technology in which all spindles are switched at the same time, the noise generated when the spindle seats 19 are switched can be reduced.

[0044] Example 2

[0045] like Figure 16-17 As shown, taking 24 spindle seats 19 as an example, 12 rotors 13 are divided into six groups, and the center of each group of rotors 13 is distributed on a circumference. The circumference diameters from large to small are 357.73, 356.86, 348.36, 346.32, 338.2, and 336.81, respectively. Each rotor 13 is provided with four slots 15 in an annular array, and the cutting angle is as follows: Figure 16 As shown, there are two interior angles of 145°, four of 147°, four of 152°, and two of 155°.

[0046] In the above scheme, when the rotor 13 rotates, the spindle seats 19 are switched separately, that is, only a single spindle seat 19 is switched on one side, and only two spindle seats 19 are switched crosswise at most when the two-way left and right runways are running.

[0047] Example 3

[0048] like Figure 18 As shown, taking 40 spindle seats 19 as an example, the number of rotors 13 is 20, and the rotors 13 are divided into two groups and the two groups of rotors 13 are distributed on two circumferences, the diameters of the two circumferences are 578.45 and 571.3 respectively, there are 10 with an inner angle of 157.5° and 10 with an inner angle of 166.5°, and four slots 15 in a ring array are set on the edge of each rotor 13, and the cutting angle is as follows: Figure 18 .

[0049] In the above scheme, when the rotor 13 rotates, the spindle seats 19 are switched separately, that is, only a single spindle seat 19 is switched on one side, and only two spindle seats 19 are switched crosswise at most when the two-way left and right runways are running.

[0050] Example 4

[0051] like Figure 19As shown, taking 40 spindle seats 19 as an example, the number of rotors 13 is 20, and the 20 rotors 13 are divided into 10 groups and distributed on 10 circumferences. The diameters of the 10 circumferences are 585.8, 582.05, 581.03, 580.14, 574.51, 572.55, 571.41, 570.39, 567.34, and 563.65 respectively. The number and angle values of the inner angle and the cutting angle are as follows: Figure 19 shown.

[0052] In the above scheme, when the rotor 13 rotates, the spindle seats 19 are switched separately, that is, only a single spindle seat 19 is switched on one side, and only two spindle seats 19 are switched crosswise at most when the two-way left and right runways are running.

[0053] Example 5

[0054] like Figure 20 As shown, taking 48 spindle seats 19 as an example, the number of rotors 13 is 24, and the rotors 13 are divided into two groups, and the two groups of rotors 13 are distributed on two circles with diameters of 693.98 and 682.1 respectively. There are 12 rotors with an internal angle of 157.5° and 12 rotors with an internal angle of 172.5°. The value and number of the cut-in angles are as follows: Figure 20 shown.

[0055] In the above scheme, when the rotor 13 rotates, the spindle seats 19 are switched separately, that is, only a single spindle seat 19 is switched on one side, and only two spindle seats 19 are switched crosswise at most when the two-way left and right runways are running.

[0056] According to different internal angle designs, a non-circular transmission gear structure is obtained, so that the spindle seats on the rotor 13 are separated and crossed in sequence according to different angles, and when crossing and switching, they are switched and run in sequence according to different angles. At most, only two spindle seats are switched at the same time, which can greatly reduce noise and extend the life of the equipment.

[0057] In the above embodiment, Figure 14-20 In any figure, the circle with the largest diameter is the circumference of the rotor 13 distribution, the circle with the smallest diameter represents the spindle seat 19, and the circle with the middle diameter represents the rotor 13. The intersection of the vertical cross line inside the rotor 13 and the rotor 13 represents the setting point of the slot 15. The angle inside the circle with the largest diameter is the inner angle, and the angle marked outside is the cut-in angle. The position pointed by the horizontal line with the arrow is the intersection position of the spindle seat 19, that is, when the slots 15 on the edges of two adjacent rotors 13 are aligned, the spindle seat 19 will intersect. Figure 19 In the figure, since there are 10 rotors 13 distributed around the circumference and they are relatively dense, they are not shown and are only annotated with the radius.
